Does anyone have a copy of a wiring diagram for an '01 RAM. I swapped out my 3.9 for a 5.9 in my Dakota, But I don't have any gauges. The truck runs, but I'm pretty sure that the wiring is a little different from the RAM to the Dak. Any help is appreciated.

 

Check in the FAQ section here, there is a downloadable version of the 01 service manual. It has wiring diagrams in it.

 

It needs a PCM and wire harness from a 5.9 I would think. Maybe just the PCM, I'm not sure. If you have not already done that. Here is the link for the manual https://dodgeforum.com/forum/2nd-gen...-gen-rams.html . I'm amazed it runs if you are using the 3.9 PCM.
